摘  要:大兴安岭北段是大兴安岭成矿带的重要组成部分,其中铜矿是北段的主要矿种,以斑岩型为主,矿床规模大,经济价值和科学研究意义重大.本文在系统总结大兴安岭北段区域地质背景、不同时代铜矿床成矿地质作用的的基础上,综述了大兴安岭北段近年来找矿勘查的新成果,并提出额尔古纳地块西缘、兴安地块东南缘及两地块缝合带处是寻找铜矿的重要方向,“就矿找矿”“攻深找盲”也是大兴安岭北段铜矿勘查的重点.The northern Daxinganling Mountains is an important part of Daxinganling metallogenic belt,where copper is the main mineral,dominated by porphyry type,large in scale,with great economic value and scientific research significance.Based on the systematic summary of regional geological background and mineralization process of copper deposits in different ages in northern Daxinganling Mountains,the paper summarizes the new exploration results in the area in recent years,and points out that the western margin of Ergun block,southeastern margin of Xing’an block,and suture zone of the two blocks are important for copper deposit prospecting.Attention should be also paid nearby the existing deposits and blind orebodies in the deep for the exploration of copper deposits in northern Daxinganling Mountains.
